The Laguna State Polytechnic University (LSPU) is a state university in the Province of Laguna, Philippines. It has four regular campuses in three municipalities and a city of the province: LSPU-Main Campus in the capital town of Santa Cruz, LSPU-Host Campus in Siniloan, LSPU-San Pablo City Campus, and LSPU-Los Baños Campus. The university has two satellite campuses — LSPU-Nagcarlan and LSPU-RECS Complex in Santa Cruz — and two International Language Studies Centers in Thai Nguyen University, Vietnam, and Changwon College, South Korea. The Laguna State Polytechnic University was first known in 1952 as the Baybay Provincial High School, the first public high school established in the Baybay District. Expansions in infrastructures and projects/programs have been completed because the enrollment has been increasing. In 1957, by virtue of Republic Act 1807, it was converted into an agricultural school known as the Baybay National Agricultural and Vocational School. After the realization of a need for a college in the eastern portion of the province, the school was then elevated to Baybay National College of Agriculture and Technology in 1971 by virtue of Republic Act 6327.
